ALARM.

Application filed May S, 1826. Serial No. 1.0?,719.

The ehief novelty lies in the use of a soft,-

malleable metal book which passes around the clapper in the alarm and holds the same silent.

Still other novelty lies in the means employed for always keeping the alarm line tant.

Fur-ther novelty 'will be shown in the drawings and specification.

in the drawings like numeruls designate similar parts.

In the drawing& Figur-e 1 :is a diagrammatic view showing the sign-al system installed in a number ot' compartments.

Figure 2 a side elevation of the installed system in one compartment.

Figure 3 is a pcrsiective of the signal showing the hook holding the alarm inoperative with the springs which are at the end of the system on each floor.

Referring to the drawings, numeral 1 (les ignates a cord to which is attached at both ends, a spring 2. In line with the cord l is an alarm 3 with a clapper member t.. Opposite the clapper member e attacbed to the cord 1 is a soft, malleable hook 5 capable of engaging elapper member l. here the cord passes through a partition, tubes 6 are usech and where the cord 1 makes a turn, pulleys 7 are used. Eyelets 8 Carry the cord 1 along the walls.

As the alarm actually opcrates` when a 'tire brealts out in any one room the flames will ignite the cord 1 and sever same,

'and since the cord l is under tension the book 5, which is forn'ed of' soft; malleable metal will straighten out and release the clapper at in every compartment thus giving a warning to any occupants who may be in the compartments. In case there are occupants of the compartment where the fire breaks out and the flames have not reached such iutensity as to ignite the cord 1 the occupant who disco ers the lire may either sever the cord l or pull the same and thus release the soft. malleable hool s 5 from around the clappers 4: in each compartment. By using a book 5 of the described material, u i nee is no danger ot the hook e falling back into place and re-engaging the clapper member 4: as might be the case if a fieXibl-e material or a different device Were used.

Having` described my invention what I claim as new is:

1. A n'echanically operated signal having a sound producing member, a soft malleable retaining member 'mounted on acord, said retaining member normally engaging said sound producing member to retain same nactive, and operable means for releasing said i'etaining member.

2. A meehanically operatedsignal having a sound producing member, a soft malleable book mounted on a cord, said hook normally engaging said sound producing member to retain same nactive, spring operable means for straightening said hook and thereby releasing said sound producing member.

3. A. mechanically operated signal, having a sound producing member, a soft nonflexible malleable hook mounted on a cord, said book normally engaging said sound producing member to retain same inactive, and operable means for straightening said hool: thereby releasing said sound producing member.

4. A meclanically operated signal having a sound producing member, 'a soft nonfiexible, malleable hook mounted on a cord, said hook normally engaging said sound producing member to retain same inactive, spring operable means for straightening said hook and thereby forming means for releasing said sound producing member.

5. A mechanieally operated signal having a' sound producing member, a soft malleable hook normally engaging a sound producing member to retain same nactive, an inflammable cord under tension, said inflammable cord having the soft, malleable hook attached thereto and capable of straightening said hook When the cord ignites.

(i. A mechanically operated signal system for a building having a plurality of compaitments, a sound producing membel` in every eompartment, a soft malleable hook mounted on an inflammable cord, said hook normally engaging the sound producing member to retain same inactive, and operable means for pulling said hook to straighten the same, and thereby release said sound producing member in every compartment.

7. A mechanically operated signal system for a building having a plurality of compartments, a sound producing member in every compartment, a soft malleable hook mounted on *arinfiammable cord, said hook normally engagg the Sound prodcing member to retan same nactve, and operable spring means for pulling said book to straghten the same, and thereby release said sound producng member in every compartment.
